DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

In the following detailed description, reference is made to the accompanying drawing figures which form a part hereof, and which show by way of illustration specific embodiments of the invention. It is to be understood by those of ordinary skill in this technological field that other embodiments may be utilized, and structural, electrical, as well as procedural changes may be made without departing from the scope of the present invention. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or similar parts.

As used herein, the suffixes ‘module’, ‘unit’ and ‘part’ are often used for elements in order to facilitate discussion of the disclosure. Therefore, significant meanings or roles are not given to the suffixes themselves and it is understood that the ‘module’, ‘unit’ and ‘part’ can be used together or interchangeably.

Various types of terminals may be implemented using the various techniques discussed herein. Examples of such terminals include mobile as well as stationary terminals, such as mobile phones, user equipment, smart phones, DTV, computers, digital broadcast terminals, personal digital assistants, portable multimedia players (PMPs), navigators, and the like. By way of non-limiting example only, further description will be with regard to a mobile terminal 100, and such teachings may apply equally to other types of terminals.

FIG. 1 is a block diagram of a mobile terminal 100 in accordance with an embodiment of the present invention. FIG. 1 shows the mobile terminal 100 having a wireless communication unit 110, an A/V (audio/video) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, a power supply unit 190, among other components. Mobile terminal 100 is shown having various components, but it is understood that implementing all of the illustrated components is not a requirement as greater or fewer components may alternatively be implemented.

First of all, the wireless communication unit 110 typically includes one or more components which permits wireless communication between the mobile terminal 100 and a wireless communication system or network within which the mobile terminal 100 is located. For instance, the wireless communication unit 110 can include a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, a position-location module 115, and the like.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast managing server via a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel. The broadcast managing server generally refers to a server which generates and transmits a broadcast signal and/or broadcast associated information or a server which is provided with a previously generated broadcast signal and/or broadcast associated information and then transmits the provided signal or information to a terminal. The broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. If desired, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal.

The broadcast associated information includes information associated with a broadcast channel, a broadcast program, a broadcast service provider, etc. This broadcast associated information can also be provided via a mobile communication network. In this case, the broadcast associated information can be received by the mobile communication module 112.

The broadcast associated information can be implemented in various forms. For instance, broadcast associated information may include an electronic program guide (EPG) of digital multimedia broadcasting (DMB) and electronic service guide (ESG) of digital video broadcast-handheld (DVB-H).

The broadcast receiving module 111 may be configured to receive broadcast signals transmitted from various types of broadcast systems. By nonlimiting example, such broadcasting systems include digital multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcast-handheld (DVB-H), the data broadcasting system known as media forward link only (MediaFLO®) and integrated services digital broadcast-terrestrial (ISDB-T). Optionally, the broadcast receiving module 111 can be configured to be suitable for other broadcasting systems as well as the above-identified digital broadcasting systems.

The broadcast signal and/or broadcast associated information received by the broadcast receiving module 111 may be stored in a suitable device, such as a memory 160.

The mobile communication module 112 transmits/receives wireless signals to/from one or more network entities (e.g., base station, external terminal, server, etc.). Such wireless signals may represent audio, video, and data according to text/multimedia message transceiving, among others.

The wireless internet module 113 supports Internet access for the mobile terminal 100. This module may be internally or externally coupled to the mobile terminal 100. In this case, the wireless Internet technology can include WLAN (Wireless LAN) (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access), and the like.

The short-range communication module 114 facilitates relatively short-range communications. Suitable technologies for implementing this module include radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), as well at the networking technologies commonly referred to as Bluetooth and ZigBee, to name a few.

The position-location module 115 identifies or otherwise obtains the location of the mobile terminal 100. If desired, this module may be implemented with a global positioning system (GPS) module.

Referring still to FIG. 1, the audio/video (A/V) input unit 120 is shown configured to provide audio or video signal input to the mobile terminal 100. As shown, the A/V input unit 120 includes a camera 121 and a microphone 122. The camera 121 receives and processes image frames of still pictures or video, which are obtained by an image sensor in a video call mode or a photographing mode. Typically, the processed image frames can be displayed on the display 151.

The image frames processed by the camera 121 can be stored in the memory 160 or can be externally transmitted via the wireless communication unit 110. Optionally, two or more cameras 121 can be provided to the mobile terminal 100 according to the environment in which the terminal used to according to user needs.

The microphone 122 receives an external audio signal while the portable device is in a particular mode, such as phone call mode, recording mode and voice recognition mode. This audio signal is processed and converted into electric audio data. The processed audio data is transformed into a format transmittable to a mobile communication base station via the mobile communication module 112 in case of a call mode. The microphone 122 typically includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.

The user input unit 130 generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, a jog switch, and the like.

The sensing unit 140 provides sensing signals for controlling operations of the mobile terminal 100 using status measurements of various aspects of the mobile terminal. For instance, the sensing unit 140 may detect an open/close status of the mobile terminal 100, relative positioning of components (e.g., a display and keypad) of the mobile terminal 100, a change of position of the mobile terminal 100 or a component of the mobile terminal 100, a presence or absence of user contact with the mobile terminal 100, orientation or acceleration/deceleration of the mobile terminal 100.

As an example, consider the mobile terminal 100 being configured as a slide-type mobile terminal. In this configuration, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include the sensing unit 140 sensing the presence or absence of power provided by the power supply 190, the presence or absence of a coupling or other connection between the interface unit 170 and an external device. If desired, the sensing unit 140 can include a proximity sensor 141.

Therefore, the sensing unit 140 generates a sensing signal by detecting one of motions in various shapes through a location change and a direction change of the mobile terminal 100. And, at least one function can be executed to correspond to the sensing signal in accordance with each of the motions. Moreover, the relation between the motion and the function executed through the corresponding motion can be saved in the memory unit.

And, the sensing unit 140 is able to sense whether a power is supplied by the power supply unit 190, whether an external device is connected to the interface unit 170, and the like. Besides, the sensing unit 140 can include a proximity sensor 141.

The output unit 150 generates outputs relevant to the senses of sight, hearing, touch and the like. In some cases, the output unit 150 includes the display 151, an audio output module 152, an alarm unit 153, a haptic module 154, a projector module 155, and the like.

The display 151 is typically implemented to visually display (output) information associated with the mobile terminal 100. For instance, if the mobile terminal is operating in a phone call mode, the display will generally provide a user interface (UI) or graphical user interface (GUI) which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal 100 is in a video call mode or a photographing mode, the display 151 may additionally or alternatively display images which are associated with these modes, the UI or the GUI.

The display module 151 may be implemented using known display technologies including, for example, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display and a three-dimensional display. The mobile terminal 100 may include one or more of such displays.

Some of the above displays can be implemented in a transparent or optical transmissive type, which can be named a transparent display. As a representative example for the transparent display, there is TOLED (transparent OLED) or the like. A rear configuration of the display 151 can be implemented in the optical transmissive type as well. In this configuration, a user is able to see an object in rear of a terminal body via the area occupied by the display 151 of the terminal body.

At least two displays 151 can be provided to the mobile terminal 100 in accordance with the implemented configuration of the mobile terminal 100. For instance, a plurality of displays can be arranged on a single face of the mobile terminal 100 in a manner of being spaced apart from each other or being built in one body. Alternatively, a plurality of displays can be arranged on different faces of the mobile terminal 100.

In the case where the display 151 and a sensor for detecting a touch action (hereinafter also referred to a ‘touch sensor’) configures a mutual layer structure (hereinafter also referred to a ‘touchscreen’), the user can use the display 151 as an input device as well as an output device. In this case, the touch sensor can be configured as a touch film, a touch sheet, a touchpad or the like.

The touch sensor can be configured to convert a pressure applied to a specific portion of the display 151 or a variation of a capacitance generated from a specific portion of the display 151 to an electric input signal. Moreover, it is able to configure the touch sensor to detect a pressure of a touch as well as a touched position or size.

If a touch input is made to the touch sensor, signal(s) corresponding to the touch is transferred to a touch controller. The touch controller processes the signal(s) and then transfers the processed signal(s) to the controller 180. Therefore, the controller 180 is able to know whether a prescribed portion of the display 151 is touched.

With continued reference to FIG. 1, a proximity sensor (not shown in the drawing) can be provided to an internal area of the mobile terminal 100 enclosed by the touchscreen or proximate to the touchscreen. The proximity sensor is the sensor that detects a presence or non-presence of an object approaching a prescribed detecting surface or an object existing around the proximity sensor using an electromagnetic field strength or infrared ray without mechanical contact. Hence, the proximity sensor has durability longer than that of a contact type sensor and also has utility wider than that of the contact type sensor.

The proximity sensor can include one or more of a transmissive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a radio frequency oscillation proximity sensor, an electrostatic capacity proximity sensor, a magnetic proximity sensor, an infrared proximity sensor, and the like. When the touchscreen includes the electrostatic capacity proximity sensor, it may also be configured to detect the proximity of a pointer using a variation of electric field according to the proximity of the pointer. In this scenario, the touchscreen (touch sensor) can be classified as a proximity sensor.

In the following description, for clarity, an action that a pointer approaches without contacting with the touchscreen to be recognized as located on the touchscreen is referred to as ‘proximity touch’ while an action that a pointer actually touches the touchscreen may be referred to as a ‘contact touch’. The meaning of the position on the touchscreen proximity-touched by the pointer refers to the position of the pointer which vertically opposes the touchscreen when the pointer performs the proximity touch.

The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch duration, a proximity touch position, a proximity touch shift state, etc.). In addition, information corresponding to the detected proximity touch action and the detected proximity touch pattern can be outputted to the touchscreen.

The audio output module 152 functions in various modes including a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, a broadcast reception mode and the like to output audio data which is received from the wireless communication unit 110 or is stored in the memory 160. During operation, the audio output module 152 outputs audio relating to a particular function (e.g., call received, message received, etc.). The audio output module 152 is often implemented using one or more speakers, buzzers, other audio producing devices, and combinations thereof.

The alarm unit 153 is output a signal for announcing the occurrence of a particular event associated with the mobile terminal 100. Typical events include a call received event, a message received event and a touch input received event. The alarm unit 153 is able to output a signal for announcing the event occurrence by way of vibration as well as video or audio signal. The video or audio signal can be outputted via the display 151 or the audio output unit 152. Hence, the display 151 or the audio output module 152 can be regarded as a part of the alarm unit 153.

The haptic module 154 generates various tactile effects that can be sensed by a user. Vibration is a representative one of the tactile effects generated by the haptic module 154. Strength and pattern of the vibration generated by the haptic module 154 are controllable. For instance, different vibrations can be outputted in a manner of being synthesized together or can be outputted in sequence.

The haptic module 154 is able to generate various tactile effects as well as the vibration. For instance, the haptic module 154 generates the effect attributed to the arrangement of pins vertically moving against a contact skin surface, the effect attributed to the injection/suction power of air though an injection/suction hole, the effect attributed to the skim over a skin surface, the effect attributed to the contact with electrode, the effect attributed to the electrostatic force, the effect attributed to the representation of hold/cold sense using an endothermic or exothermic device and the like.

The haptic module 154 can be implemented to enable a user to sense the tactile effect through a muscle sense of finger, arm or the like as well as to transfer the tactile effect through a direct contact. Optionally, at least two haptic modules 154 can be provided to the mobile terminal 100 in accordance with the corresponding configuration type of the mobile terminal 100.

The projector module 155 is the element for performing an image projector function using the mobile terminal 100. And, the projector module 155 is able to display an image, which is identical to or partially different at least from the image displayed on the display 151, on an external screen or wall according to a control signal of the controller 180.

In particular, the projector module 155 can include a light source (not shown in the drawing) generating light (e.g., laser) for projecting an image externally, an image producing element (not shown in the drawing) for producing an image to output externally using the light generated from the light source, and a lens (not shown in the drawing) for enlarging the image for output externally at predetermined focus distance. The projector module 155 can further include a device (not shown in the drawing) for adjusting an image projected direction by mechanically moving the lens or the whole module.

The projector module 155 can be classified into a CRT (cathode ray tube) module, an LCD (liquid crystal display) module, a DLP (digital light processing) module or the like according to a device type of a display means. In particular, the DLP module is operated by the mechanism of enabling the light generated from the light source to reflect on a DMD (digital micro-mirror device) chip and can be advantageous for the downsizing of the projector module 151.

Preferably, the projector module 155 can be provided in a length direction of a lateral, front or backside direction of the mobile terminal 100. It is understood that the projector module 155 can be provided to any portion of the mobile terminal 100 according to the necessity thereof.

Subsequently, the holography module 156 may include a holography storing medium and a holography output module. And, the holography module 156 may be able to project a holography image externally.

The holography storing medium is the storing medium for recording an interference pattern generated from interference between an applied object wave and a reference wave and may be formed of such a material reacting with light intensity as photopolymer and the like.

In this case, the holography output module applies a reconstructing wave equal to the reference wave to the holography output module and then outputs a holography image generated from the diffraction effect between the applied reconstructing wave and the interference pattern recorded in the holography storing medium, under the control of the controller 180.

A holography image projecting method shall be described in detail with reference to FIGS. 4 to 7 later.

In the above description, the holography storing medium and the holography output module are implemented in a manner of being included together in the holography module 156, which is just exemplary. Alternatively, the holography storing medium and the holography output module may be separately configured and included in the mobile terminal 100.

The memory unit 160 is generally used to store various types of data to support the processing, control, and storage requirements of the mobile terminal 100. Examples of such data include program instructions for applications operating on the mobile terminal 100, contact data, phonebook data, messages, audio, still pictures, moving pictures, etc. And, a recent use history or a cumulative use frequency of each data (e.g., use frequency for each phonebook, each message or each multimedia) can be stored in the memory unit 160. Moreover, data for various patterns of vibration and/or sound outputted in case of a touch input to the touchscreen can be stored in the memory unit 160.

Moreover, in order to support the holography image projection of the holography module 156, information on the holography interference pattern may be saved. In particular, user's voice, application activated result and the like can be externally outputted via the holography module 156 using the information saved in the memory unit 160.

The memory 160 may be implemented using any type or combination of suitable volatile and non-volatile memory or storage devices including hard disk, random access memory (RAM), static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disk, multimedia card micro type memory, card-type memory (e.g., SD memory, XD memory, etc.), or other similar memory or data storage device. And, the mobile terminal 100 is able to operate in association with a web storage for performing a storage function of the memory 160 on the Internet.

Meanwhile, the sensing unit 140 is able to generate a sensing signal by detecting one of motions in various shapes through the location and direction changes of the mobile terminal 100. And, at least one function can be executed to correspond to the sensing signal in accordance with each of the motions. Moreover, the relation between the motion and the function executed through the corresponding motion can be saved in the memory unit 160.

The interface unit 170 is often implemented to couple the mobile terminal 100 with external devices. The interface unit 170 receives data from the external devices or is supplied with the power and then transfers the data or power to the respective elements of the mobile terminal 100 or enables data within the mobile terminal 100 to be transferred to the external devices. The interface unit 170 may be configured using a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for coupling to a device having an identity module, audio input/output ports, video input/output ports, an earphone port and/or the like.

The identity module is the chip for storing various kinds of information for authenticating a use authority of the mobile terminal 100 and can include User Identify Module (UIM), Subscriber Identity Module (SIM), Universal Subscriber Identity Module (USIM) and/or the like. A device having the identity module (hereinafter called ‘identity device’) can be manufactured as a smart card. Therefore, the identity device is connectible to the mobile terminal 100 via the corresponding port.

When the mobile terminal 110 is connected to an external cradle, the interface unit 170 becomes a passage for supplying the mobile terminal 100 with a power from the cradle or a passage for delivering various command signals inputted from the cradle by a user to the mobile terminal 100. Each of the various command signals inputted from the cradle or the power can operate as a signal enabling the mobile terminal 100 to recognize that it is correctly loaded in the cradle.

The controller 180 typically controls the overall operations of the mobile terminal 100. For example, the controller 180 performs the control and processing associated with voice calls, data communications, video calls, etc. The controller 180 may include a multimedia module 181 that provides multimedia playback. The multimedia module 181 may be configured as part of the controller 180, or implemented as a separate component. Moreover, the controller 180 is able to perform a pattern recognizing process for recognizing a writing input and a picture drawing input carried out on the touchscreen as characters or images, respectively.

The power supply unit 190 provides power required by the various components for the mobile terminal 100. The power may be internal power, external power, or combinations thereof.

FIG. 2 is a front perspective diagram of a mobile terminal according to various embodiments of the present invention. The mobile terminal 100 is shown as a bar type terminal body, but the mobile terminal may alternative be implemented using other configuration such as folder-type, slide-type, rotational-type, swing-type, combinations thereof, and the like. For clarity, further disclosure will primarily relate to a bar-type mobile terminal 100, but such teachings apply equally to other types of mobile terminals.

Referring still to FIG. 2, the mobile terminal 100 includes a case (casing, housing, cover, etc.) configuring an exterior thereof. The case is shown divided into a front case 101 and a rear case 102. Various electric/electronic parts are positioned or otherwise located in a space or cavity provided between the front and rear cases 101 and 102. Optionally, at least one middle case can be further provided between the front and rear cases 101 and 102. The cases 101 and 102 may be formed by injection molding of synthetic resin or they can be formed of metal substance such as stainless steel (STS), titanium (Ti) or the like, for example.

A display 151, an audio output unit 152, a camera 121, user input units 130, a microphone 122, an interface 170 and the like can be provided to the terminal body, and more particularly, to the front case 101.

The display 151 is shown occupying the majority of a main face of the front case 101. The audio output unit 151 and the camera 121 are provided to an area adjacent to one of both end portions of the display 151, while the user input unit 131 and the microphone 122 are provided to another area adjacent to the other end portion of the display 151. The user input unit 132 and the interface 170 can be provided to lateral sides of the front and rear cases 101 and 102.

The input unit 130 is manipulated to receive a command for controlling an operation of the terminal 100. The input unit 130 may also include a plurality of manipulating units 131 and 132. The manipulating units 131 and 132 will sometimes be referred to herein as a manipulating portion and they may implement any mechanism of a tactile manner that enables a user to perform a manipulation action by experiencing a tactile feeling.

Content inputted by the first or second manipulating unit 131 or 132 can be diversely set. For instance, such a command as start, end, scroll and the like is inputted to the first manipulating unit 131. A command for volume adjustment of sound outputted from the audio output unit 152, a command for switching to a touch recognizing mode of the display 151 or the like can be input to the second manipulating unit 132.

Interconnected operational mechanism between the display 151 and the touchpad 135 are explained with reference to FIG. 3 as follows.

FIG. 3 is a front-view of terminal 100 according to various embodiment of the present invention. Various kinds of visual information can be displayed on the display 151. Such information can be displayed in characters, numerals, symbols, graphics, icons and the like. In order to input the information, at least one of the characters, numerals, symbols, graphics and icons are represented as a single predetermined array to be implemented in a keypad formation. This keypad formation is also referred to as ‘soft keys’.

FIG. 3 shows that a touch applied to a soft key is input through a front face of a terminal body. The display 151 is operable through an entire area or by being divided into a plurality of regions. In the latter case, a plurality of the regions can be configured interoperable. For instance, an output window 151 a and an input window 151 b are displayed on the display 151. A soft key 151 c representing a digit for inputting a phone number or the like is outputted to the input window 151 b. If the soft key 151 c is touched, a digit corresponding to the touched soft key is output to the output window 151 a. If the first manipulating unit 131 is manipulated, a call connection for the phone number displayed on the output window 151 a is attempted.

In addition, the display 151 or the touchpad 135 can be configured to receive a touch input by scroll. A user scrolls the display 151 or the touchpad 135 to shift a cursor or pointer located at an entity (e.g., icon or the like) displayed on the display 151. Furthermore, in case that a finger is shifted on the display 151 or the touchpad 135, a path of the shifted finger can be visually displayed on the display 151. This may be useful in editing an image displayed on the display 151.

Consider the scenario in which both the display (touch screen) 151 and the touchpad 135 are touched together within a predetermined or threshold time range, thus causing one function of the terminal can be executed. This simultaneous touch example may correspond to a case that the terminal body is held by a user using a thumb and a first finger (clamping). The above function can include activation or deactivation for the display 151 or the touchpad 135.

In the following description, a method of representing a holography image in a mobile terminal and a structure therefor, which are applicable to embodiments of the present invention, are explained as follows.

Prior to the detailed description of holography image, a configuration of a mobile terminal including a holography module 156 is described with reference to FIG. 4.

First of all, the holography module 156 may be installed in the mobile terminal in a manner of being loaded on a front side or backside of the mobile terminal.

FIG. 4 is a diagram of a mobile terminal including a holography module according to one embodiment of the present invention.

Referring to FIG. 4A, the holography module 156 is provided to the front side of the mobile terminal. In particular, the holography module 156 may be provided to the front side of the mobile terminal together with the camera 121. And, the holography module 156 may be able to project and display a holography image 411 created under the control of the controller 180.

Referring to FIG. 4B, the holography module 156 may be provided to a prescribed portion of the backside of the mobile terminal. In particular, the holography module 156 may be included together with the camera 121. And, the holography module 156 may be able to project and display a holography image 412 created under the control of the controller 180.

The holography images implemented through the holography module 156 may include a planar image and a stereoscopic image both.

In particular, the stereoscopic image implemented through the holography module 156 may be mainly classified into a 2D (2-dimensional) stereoscopic image and a 3D (3-dimensional) stereoscopic image.

Substantially, a 2D stereoscopic image system is a monoscopic system that provides the same image to both eyes. In particular, according to the 2D stereoscopic image system, a polyhedron created using at least one point, at least one line, at least one plane and a combination thereof is placed in a virtual stereoscopic space and an image generated from viewing the placed polyhedron in a specific view is then displayed, under the control of the controller 180.

A 3D stereoscopic image system is a stereoscopic system that provides different images to both eyes, respectively. And, the 3D stereoscopic image system adopts the principle of sensing a 3D effect of an object viewed via bare eyes of a human. In particular, human eyes sense different planar images in viewing the same object due to a distance between both eyes. The sensed different planar images are delivered to a brain through retinas. And, the brain synthesizes the delivered different images together to sense depth and reality of the corresponding stereoscopic image. Although there is a slight difference between humans, binocular disparity attributed to a distance between both eyes enables a 3D effect. Thus, the 3D stereoscopic image system may correspond to a method of displaying an image using this binocular disparity.

Holography image created through the holography module 156 may include both of the planar image and the stereoscopic image. For clarity and convenience of the following description, assume that the holography image may be displayed by the 2D stereoscopic image system, by which the present invention may be non-limited.

In the following description, a method of representing a holography image in a mobile terminal and a structure therefor, which are applicable to embodiments of the present invention, are explained in detail as follows.

First of all, a holography image representing method may be understood as an image displaying method of simultaneously cumulating and playing all informations (i.e., amplitude and phase) on a light (i.e., wave motion), whereas a related art image is a recording of distribution of bright and dark sides of an object.

A holography image representing method is described with reference to FIG. 5 as follows.

FIG. 5 is a diagram for explaining holography principle conceptionally.

Referring to FIG. 5 (a), a coherent light from a laser beam source 501 is slit into two beams via a splitter 502.

In particular, if one of the two beams is applied to a subject 507, a surface of the subject reflects the corresponding light. And, this beam will be named an object wave in the following description.

The other beam is diffused through a lens 506 to be directly applied to a front face of a holography photosensitive material 505. And, this beam will be named a reference wave in the following description. Reflectors 503, 504 and 508 are also shown.

As the object wave and the reference wave cause an interference effect in-between, about 500˜1,500 delicate and complicated interference patterns per 1 mm are generated. And, a photo of recording these interference patterns is called a hologram.

Referring to FIG. 5 (b), if such a beam as the generated reference wave is projected on the photosensitive material 505, a light diffracts at a position different from an incident direction of the reference wave in a manner of being affected by the interference patterns. Subsequently, the diffractive lights gather together to form the light initially reflected by the object. Hence, a holography image 509 is projected. In particular, an initial object wave is reconstructed from hologram. And, an image representing method using the reconstructed initial object wave may be named a holography image representing method.

Looking into an inside of a reconstructed wave surface, an object is initially seen as if situated inside. If a viewing point moves, a viewed position of the object changes correspondingly. Moreover, since an original wave surface of the object is reconstructed, it may interfere with a wave surface coming from a slightly modified object.

A holography image representing method may be classified into a transmittive type holography image representing system and a reflective type holography image display system.

(1) Transmittive Type Holography Image Representing System

According to the transmittive type holography image representing system, an image generated from light, which transmits a hologram if applied in rear of the hologram, is observed in front of the hologram. In the transmittive type holography image representing system, an object wave and a reference wave are applied to a photo film in the same direction to generate a holography image. And, the generated holography image is characterized in having clear and bright colors.

(2) Reflective Type Holography Image Displaying System

According to the reflective type holography image displaying system, an image generated from light, which is reflected if applied in front of the hologram, is observed in front of the hologram. In the reflective type holography image displaying system, an object wave and a reference wave are incident on a photosensitive material in directions opposite to each other, respectively. And, the holography image generated by the reflective type holography image displaying system is characterized in having an excellent 3D effect.

The transmittive type holography image representing system and the reflective type holography image displaying system are described in detail with reference to FIG. 6 and FIG. 7 as follows.

FIG. 6 is a diagram for conceptionally explaining a transmittive type holography system.

Referring to FIG. 6A, a light from a laser beam source 601 passes through a lens 602 and then through a spatial filter 603 and is then spread as a smooth spherical wave. The spherical wave is reflected by reflector 604 and is split into two beams by a 50:50 beam splitter 605. One of the two beams of the spherical wave is reflected by reflector 606 and illuminates, an object 608 to produce an object wave, while the other is reflected by reflector 609 and intactly illuminates a film 607 to produce a reference wave. In doing so, the object wave created from the object 608 illuminates the film 607 as well.

Subsequently, the object and reference waves having illuminated the film 607 cause an interference effect on each other to produce an interference pattern. The interference pattern is then imprinted on the film 607.

In particular, referring to FIG. 6B, the object wave and the reference wave are projected on the same surface of the film 607 to produce the interference pattern.

Subsequently, referring to FIG. 6C, if the reference wave is projected on the film 607, an object wave transmits in a direction of a surface opposite to the incident surface of the previous object and reference waves, thereby creating a holography image.

FIG. 7 is a diagram for conceptionally explaining a reflective type holography system.

Referring to FIG. 7A, like FIG. 6A, a light from a laser beam source 701 passes through a lens 702 and then through a spatial filter 703 and is then spread as a smooth spherical wave. The spherical wave is split into two beams by a 50:50 beam splitter 705. One of the two beams of the spherical wave illuminates an object 708 to produce an object wave, while the other intactly illuminates a film 707 to produce a reference wave. Reflectors 704, 706 and 709 are also illustrated.

Unlike FIG. 6A, FIG. 7A shows that the reference wave and the object wave illuminate the film 707 in directions opposite to each other, respectively.

In particular, the reference wave is projected on a left surface of the film 707 and the object wave is projected on a right top surface of the film 707. Subsequently, referring to FIG. 7C, if the reference wave is projected on the film, the object wave transmits the film in opposite direction to create a holography image.

In the above descriptions, each of the films 607 and 707 is represented as a holography storing medium and another component capable of creating a holography image by emitting a light to the film is represented as a holography output module in this specification.

As mentioned in the foregoing description, for clarity and convenience of the description of this specification, the holography storing medium and the holography output module are implemented in a manner of being included in the holography module 156, which is just exemplary. Alternatively, the holography storing medium and the holography output module may be included as separate components in the mobile terminal 100.

For clarity and convenience, assume that a mobile terminal mentioned in the following description includes at least one of the components shown in FIG. 1 and that a display unit 151 includes a touchscreen.

Generally, a graphic of an arrow or finger type to point out a specific object or select a menu on the display unit 151 is called a pointer or a cursor.

Specifically, the pointer may be frequently regarded as a finger or a stylus pen for a touch manipulation or the like.

In this specification, in order to clearly discriminate the pointer and the cursor from each other, a graphic displayed on the display unit 151 may be named a cursor, while such a physical means for performing a touch, a proximity touch, a gesture and the like as a finger, a stylus pen and the like may be named a pointer.

As mentioned in the foregoing description, a holography image may include a planar image and a stereoscopic image both. For clarity and convenience of the following description, assume that a holography image is displayed by 2D stereoscopic image system.

Meanwhile, a holography image according to one embodiment of the present invention may be displayed in accordance with a set holography pattern.

In this case, the holography pattern may mean that a holography image projected via the holography module 156 is changed into a preset pattern in accordance with a time so as to be provided to a user.

The holography pattern may be set in various ways as follows.

First of all, it may be able to set a holography pattern in a manner of varying a distance difference between a holography output module and a holography image in accordance with time.

In particular, as the distance difference between the holography output module 156 and the holography image is changed in accordance with time, the holography image projected via the holography module 156 may be shifted upward and downward, thereby enabling a setting of a prescribed holography pattern.

It may be able to set a holography pattern in a manner of varying a shape of a holography image projected by the holography module 156.

For instance, the controller 180 controls a holography image projected by the holography module 156 to have a circular shape in the first time and then controls the pattern of the holography image to be changed into a rectangular shape. Thus, as the shape of the holography image is changed into various forms in accordance with time, a setting of the holography pattern is enabled.

It may be able to apply a method of shifting or rotating a holography image projected by the holography module 156 in right or left direction.

In particular, while a distance difference between a holography module and a holography image is constantly maintained, it may be able to set a holography pattern in a manner of moving or rotating the projected holography image in right and left directions in accordance with time or rotating the projected holography image by moving it in right and left directions.

It may be able to set a holography pattern in a manner of modifying a color or size of a projected holography image in accordance with time or controlling a holography image to flicker. And, it may be able to set a holography pattern in a manner of controlling at least one of projection brightness, play frequency, illumination, vibration feedback, sound insertion, image insertion, repetitive projection and the like.

Although the above description is based on the assumption that a holography pattern is set by an individual factor, it may be able to set a holography pattern by a plurality of factors.

For instance, it may be able to set a holography pattern in a manner of moving an rotating a projected holography image in left and right directions by changing a distance difference between the holography module 156 and a holography image in accordance with time.

The above description is made on the assumption that a holography pattern is set for a whole holography image, which is just exemplary. Optionally, it may be able to apply a holography pattern to a prescribed portion of the holography image.

In the following description, a holography pattern set for a holography image is explained in detail with reference to FIGS. 8 to 10.

First of al, a holography pattern may be set in a manner of adjusting a distance difference between a holography image and a terminal.

In particular, a holography pattern may be controlled to display a pattern of moving a projected holography image upward and downward by increasing or decreasing a distance difference between a holography image and a terminal in accordance with time.

This is described with reference to FIG. 8 as follows.

FIG. 8 is a diagram for one example of setting a holography pattern by adjusting a distance difference between a holography image and a terminal according to one embodiment of the present invention.

Referring to FIG. 8A, a distance difference between a holography image and a terminal is set to increase in proportion to time.

Referring to FIG. 8B, a holography image projected from a terminal moves upward by getting distant from the terminal as time goes by. If the total time set in FIG. 8A expires, the projected holography image disappears.

Hence, by adjusting a distance difference between a holography image and a terminal, it may be able to form a pattern of moving a projected holography image upward and downward.

It may be able to control a holography pattern to be set by changing a projected shape of a holography image.

In particular, by moving an image projected by the holography module 156 in right and left directions, rotating the projected image, or changing a size of the projected image, it may be able to change a shape of a projected holography image.

In the above description, a holography pattern may be formed by moving or rotating an image, which is exemplary. Alternatively, it may be able to form a holography pattern in a manner of changing a displayed shape by maintaining a same distance difference between a terminal and a projected holography image.

This is described with reference to FIG. 9 as follows.

FIG. 9 is a diagram for one example of setting a holography pattern by modifying a holography projected shape according to one embodiment of the present invention.

Referring to FIG. 9A, a projected holography image is set to rotate by maintaining the same distance from a terminal.

Accordingly, referring to FIG. 9B, the image projected from the terminal rotates in accordance with elapse of time by maintaining the same distance difference from the terminal.

Moreover, it may be able to set a holography pattern by changing a distance difference between a holography image and a terminal and a shape of a projected holography image together.

In particular, it may be able various kinds of holography patterns by changing a distance difference between a holography image and a terminal in accordance with time and also changing a shape of the holography image

This is described with reference to FIG. 10 as follows.

FIG. 10 is a diagram for one example of setting a holography pattern by adjusting a distance difference and a holography projected shape according to one embodiment of the present invention.

Referring to FIG. 10A, a distance difference between a holography image and a terminal is set to be maintained constantly, decreased and then increased in accordance with time. And, assume that the holography image is projected by rotating.

Accordingly, referring to FIG. 10B, a holography image projected by the holography module 156 is displayed by maintaining a distance difference from a terminal, a distance difference between the holography image and the terminal is decreased and then increased, while the holography image keeps being rotated and projected.

Therefore, as the holography image is moving and rotating simultaneously, it may be able to provide a user with various effects.

Meanwhile, a holography image may be projected in a manner of being included in a prescribed region of a previously designated holography background image.

A holography background image may include a closed curve implemented into a combination of at least one of a straight line, a line bent at a prescribed angle, a branch line, a curved line and the like. For instance, the closed curve shape may include one of a circle, a triangle, a quadrangle, a pentagon, a diamond shape and the like and may be implemented in various ways in accordance with user manipulations.

A holography background image, like a holography image, may be implemented by 2D stereoscopic image system or 3D stereoscopic image system. In particular, the 3D stereoscopic image system follows a stereoscopic method of providing different images to both eyes, respectively.

A content of a holography image may be displayed on a whole region or a partial region of a holography background. Moreover, a holography background is partitioned into a plurality of regions by a user manipulation to display contents of a plurality of holography images thereon.

For instance, after a holography background of a television shape has been partitioned into 4 sections, 4 different image contents may be projected as a holography image on the 4 sections, respectively.

FIG. 11 is a diagram for one example of setting a holography background according to one embodiment of the present invention.

In FIG. 11, assume that a prescribed shape is recognized via the touchscreen and that a holography background corresponding to the recognized shape is set. Yet, this assumption is just exemplary. Alternatively, it may be able to set a holography background by such a different method as a menu manipulation and the like.

Referring to FIG. 11A, an image content 1110 is projected as a holography image.

In doing so, referring to FIG. 11B, a user may input a 1st shape 1120 via the touchscreen. If the 1st shape 1120 is inputted, the controller 180 determines a holography background corresponding to the 1st shape 1120 and may control a holography image to be projected in a manner that the image content 1110 is included within the determined holography background.

The controller 180 may control the touchscreen to display a list of candidates for a plurality of holography backgrounds applicable in association with the 1st shape 1120.

In doing so, the list may be displayed as thumbnails, which is shown in FIG. 11C.

Referring to FIG. 11C, a candidate list 1130 of holography backgrounds settable to correspond to the 1st shape 1120 may be displayed as thumbnails. A user may be able to select a prescribed holography background from the displayed holography background candidate list 1130.

Referring to FIG. 11D, the controller 180 controls the holography module to output a holography image in a manner that the image content 1110 is displayed on a prescribed region within the selected holography background 1140.

FIG. 12 is a diagram for one example of displaying a plurality of image contents on a predetermined region within a holography background according to one embodiment of the present invention.

In FIG. 12, assume that a content projected as a holography image includes an image content.

In FIG. 11, assume that a prescribed shape is recognized via the touchscreen and that a holography background corresponding to the recognized shape is set. Yet, this assumption is just exemplary. Alternatively, it may be able to set a holography background by such a different method as a menu manipulation and the like.

As mentioned in the foregoing description, an image content may be displayed on a whole or partial region of a holography background and a ratio of this region may be randomly modified by a user. Moreover, a holography background is partitioned into a plurality of regions and a plurality of image contents may be displayed on a plurality of the regions, respectively.

Referring to FIG. 12A, a user may input a 1st shape 1210 via the touchscreen. If the 1st shape 1210 is inputted, the controller 180 determines a holography background 1213 corresponding to the 1st shape 1210 and may control a holography image to be projected in a manner that an image content is included within the determined holography background 1213.

In FIG. 12A, the image content is designated to be displayed on a region amounting to 80% of the holography background 1213. The region amounting to 80% of the holography background 1213 is divided into two regions 1211 and 1212. And, two image contents are displayed on the two regions 1211 and 1212 as a holography image, respectively.

Referring to FIG. 12B, a user may input a 2nd shape 1220 via the touchscreen. If the 2nd shape 1220 is inputted, the controller 180 determines a holography background 1224 corresponding to the 2nd shape 1220 and may control a holography image to be projected in a manner that an image content is included within the determined holography background 1213.

In FIG. 12B, the image content is designated to be displayed on a region amounting to 85% of the holography background 1224. The region amounting to 85% of the holography background 1224 is divided into 3 regions 1221, 1222 and 1223. And, 3 image contents are displayed on the 3 regions 1221, 1222 and 1223 as a holography image, respectively.

FIG. 13 is a diagram for a detailed example of a holography background according to one embodiment of the present invention.

In particular, FIG. 13A shows one example of implementing a holography background of an apple shape.

FIG. 13B shows one example of implementing a holography background of a calculator shape.

FIG. 13C shows one example of implementing a holography background of a character shape. In doing so, a detailed information 1313 on an object may be displayed on a prescribed region of the holography background as well.

FIG. 13D shows one example of implementing a holography background of a business card shape. In doing so, a detailed information 1314 on an object may be displayed on a prescribed region of the holography background as well.

FIG. 13E shows one example of implementing a holography background of a folder shape.

FIG. 13F shows one example of implementing a holography background of a globe shape.

FIG. 13G shows one example of implementing a holography background of a video image shape.

FIG. 13H shows one example of implementing a holography background of a gallery shape. In doing so, a plurality of image contents may be projected as a gallery shape together with the holography background.

FIG. 13I shows one example of implementing a holography background of a music image shape.

FIG. 13J shows one example of implementing a holography background of a memo shape.

FIG. 13K shows one example of implementing a holography background of a TV image shape.

Yet, the above-mentioned holography backgrounds are just exemplary. More holography backgrounds may be implemented in various ways using the closed curve shape including a closed curve implemented into a combination of at least one of a straight line, a line bent at a prescribed angle, a branch line, a curved line and the like.

Meanwhile, a user may be able to set a specific object or screen, which is to be projected as a holography image, according to one embodiment of the present invention.

First of all, an object, which can be projected as a holography image, may include one of an address book, a plurality of applications, a name of a specific object, a plurality of contents and the like. In particular one of an address book, a plurality of applications and a plurality of contents may be displayed as a holography image or a name of a specific object may be displayed as a holography image. Yet, the above description is just exemplary. Optionally, a user may be able to randomly designate a new target or change a target.

Moreover, a screen, which can be projected as a holography image, may include a whole or partial region displayed on the display unit.

In particular, a part, which will be projected as a holography image, may be set on a whole screen of the display unit. For instance, a screen amounting to 70% of the display unit may be set to be projected as a holography image.

This is described in detail with reference to FIG. 15 and FIG. 15 as follows.

FIG. 14 is a diagram for one example of an object, which can be projected as a holography image, according to one embodiment of the present invention.

Referring to FIG. 14a , a text 1411 included in a message may be to be projected as a holography image.

Referring to FIG. 14B, a specific icon 1412 among a plurality of icons may be projected as a holography image. In this case, the example is related to icons. Alternatively, a widget, an emoticon or the like may become a holography image settable target as well.

Referring to FIG. 14C, an image 1431 among informations saved in a phonebook may be set as a target to which a holography image will be applied.

FIG. 15 is a diagram for one example of a screen projected as a holography image according to one embodiment of the present invention.

Referring to FIG. 15A, a plurality of informations are displayed as a cube on a display unit.

If a user designates a specific face 1511 among a plurality of faces of the cube, on which a plurality of the informations are displayed, respectively, the designated specific face 1411 may be projected as a holography image.

In particular, a partial region displayed on a screen may be controlled to be displayed as a holography image in accordance with a holography pattern.

Referring to FIG. 15B, depths are given to a plurality of images, respectively. And a whole screen region 1512 may be controlled to be projected as a holography image.

A region corresponding to a partial image 1513 among a plurality of the images may be controlled to be projected as a holography image only.

Meanwhile, according to one embodiment of the present invention, an object, to which a holography pattern will be applied, may include a specific target or a specific group designated by a user.

This is described in detail with reference to FIG. 16 as follows.

FIG. 16 is a diagram for one example of setting a specific target or a specific group, which is projected as a holography image, according to one embodiment of the present invention.

Referring to FIG. 16A, a specific target added via an editing menu 1611 of a phonebook may be set to be projected as a holography image only.

Referring to FIG. 16B, a target sorted as a specific group via a group menu 1621 of a phonebook may be projected as a holography image only.

Therefore, it may be able to conveniently manage a specific target or group, which will be projected as a holography image, by a specific target or group unit.

Meanwhile, according to one embodiment of the present invention, a holography type is set for a specific object or screen and a holography image may be projected in accordance with the set holography type. Moreover, the controller 180 may control a prescribed visual effect to be displayed on the holography type set specific object or screen.

This is described in detail with reference to FIG. 17 as follows.

FIG. 17 is a flowchart for one example of projecting a holography image in accordance with a holography type set for a specific object or screen according to one embodiment of the present invention.

Referring to FIG. 17, a user may be able to set a holography type for a specific object or screen by a prescribed menu or key manipulation [S1710].

In this case, the holography type settable specific object may include one of an address book, a plurality of applications, a name of a specific object, a plurality of contents, a plurality of widgets and the like. A plurality of the applications may include applications related to phone, message, email, schedule, memo, camera, gallery, subway route map, electronic dictionary, calculator, compass, SNS, stock market, map and the like. A plurality of the widgets may include widgets related to phone, message, email, schedule, memo, camera, gallery, subway route map, electronic dictionary, calculator, compass, SNS, stock market, map and the like. Moreover, the holography type settable specific screen may include a whole or partial region displayed on the display unit.

Yet, the above descriptions of the specific object and the specific screen are just exemplary. And, holography types may be set for various targets that can be displayed on the display unit.

Meanwhile, the holography type set for the specific object or screen may be mainly classified into a default type, a holography background type and a holography pattern type.

First of all, a default type means that a content corresponding to a specific object or a specific screen is intactly projected as a holography image. For instance, in case that a map application is activated, a result content of the activated map application may be projected as a holography image. If a whole region of the display unit is set to be projected as a holography image, a content currently displayed on the whole region of the display unit may be projected as a holography image.

Secondly, a holography background type is a type advanced from the default type and may mean that a holography image is projected in a manner of being included in a prescribed region of the above-mentioned holography background image.

In particular, a content of a holography image is displayed in a manner of being included in a whole or partial region of a holography background.

In this case, the holography background image may include a closed curve implemented into a combination of at least one of a straight line, a line bent at a prescribed angle, a branch line, a curved line and the like and may be implemented by 2D stereoscopic image system or 3D stereoscopic image system.

Thirdly, a holography pattern type is a type advanced from the default type and may mean that a holography image is projected in a manner of varying in accordance with time to correspond to the above-mentioned holography pattern.

In particular, it may be able to set a holography pattern in a manner of changing a distance difference between a holography output module and a holography image, changing a shape of a holography image projected by the holography output module 156 in accordance with time, moving a projected holography image in right and left directions, rotating a projected image, or changing a color, size and/or the like of a projected holography image in accordance with time.

Each of the default type, the holography background type and the holography pattern type may be individually set for a specific object or screen. Optionally, a plurality of the types may be simultaneously set for a specific object or screen.

For instance, if a holography background type and a holography pattern type are simultaneously set for a map application, an activated result of the map application may be projected as a holography image in accordance with a holography pattern set by being included in a holography background.

Once the holography type is set for the specific object or screen, the controller 180 may be able to display a prescribed visual effect to inform a user of the holography type setting [S1720].

In this case, the visual effect plays a role as an indicator in informing a user that the holography type is set for the corresponding target.

This visual effect may be implemented using various effects including a pattern of surface texture, flickering, size variation, at least one shape-transformed or twisted portion and the like. Moreover, if a holography background type is set, the set background may be displayed as a shortcut or thumbnail, which will be described in detail with reference to FIGS. 24 to 28 later. Besides, the visual effect is non-limited by the above-mentioned effects. And, the visual effect may be implemented using other effects in various ways.

Thereafter, the user may be able to select the holography type set specific object or screen [S1730].

If a prescribed object or screen is selected, the controller 180 may project a holography image in accordance with the set holography type [S1740].

In particular, a content of a specific object or screen is intactly projected as a holography image. Alternatively, a search for a specific information is performed and the found specific information is then projected as a holography image. Alternatively, a specific item is projected as a holography image only in accordance with a holography type. Alternatively, one item is activated, a next item is automatically activated, and a holography image is then projected in accordance with a holography type. Alternatively, a previous of a holography type is provided and a holography image is projected. Alternatively, a plurality of functions are displayed and a holography image is projected by applying a holography type in accordance with a selected function.

First of al, the controller 180 may control a content related to a specific object or screen to be intactly projected as a holography image. For instance, a content of an activated result of a weather application may be intactly projected as a holography image.

Secondly, in case that a specific object is an informative/active type widget, a search for a specific information is performed and the found specific information may be projected as a holography image.

For instance, the informative/active type widget may include a widget for one of weather, news, stock, movie, music, gourmet restaurant, shopping, search, blog, cartoon, traffic, game, Google, Naver, digital clock, analog clock, word time clock, memo, bookmark, photo frame, map, YouTube, SNS and the like. In particular, this informative/active type widget automatically searches information to provide information actively.

For instance, after Google widget has been activated, if a user inputs a keyword ‘new technology’ by key manipulation or voice, the controller 180 makes a search for specific information related to ‘new technology’ and then controls the found specific information to be projected as a holography image.

A specific item may be projected as a holography image in accordance with a holography type only. For instance, if a ‘sports’ related specific item is selected from a news widget, a detailed content for the selected ‘sports’ related specific item may be projected as a holography image.

One item is activated, a next item is automatically activated, and a holography image may be then projected in accordance with a holography type.

For instance, if a gallery application is activated, the controller 180 may control previously designated images to be sequentially activated and displayed as holography images in prescribed time interval.

A preview of holography type is provided and a holography image may be then projected. For instance, in case that a holography background type of a rectangular shape is set for a weather application, it is preferentially displayed as a preview image in a previously designated size. If a user selects the displayed preview image, a holography image may be displayed in accordance with the holography background type.

A plurality of functions are displayed and a holography image may be then projected by applying a holography type in accordance with a selected function.

In particular, if a specific object is selected by a user, the controller 180 may display a plurality of functions each of which is capable of providing a holography image in accordance with a set holography type.

A plurality of the functions selectable by a user may include a call function, an information reading function, a message sending function, a holography type preview function and the like. And, these functions may be displayed as a list. In doing so, if a user selects a prescribed one of a plurality of the displayed functions, a holography image may be projected by applying a holography type in accordance with the selected function.

Yet, the above description is just exemplary. And, a holography image may be projected in various forms. A method of projecting a holography image will be described in detail with reference to FIGS. 29 to 34 later.

Therefore, a user may be provided with a holography image in accordance with a preset holography type. And, it may be convenient for the user to recognize that a holography type has been set using a prescribed visual effect.

FIG. 18 schematically shows the steps S1710, S1720, S1730 and S1740.

FIG. 18 is a diagram for one example of projecting a holography image in accordance with a holography type set for a specific object or screen according to one embodiment of the present invention.

Referring to FIG. 18, it may be able to set a holography type for a specific object via a prescribed setting menu 1810.

If the holography type is set, the controller 180 may give a prescribed visual effect to the holography type set specific object. A user is then able to select the holography type set specific object 1820.

If the holography type set specific object is selected, the controller 180 may project a holography image in accordance with the set holography type.

In particular, if a default type is set, a holography image 1831 may be projected. If a holography background type is selected, a holography image 1832 may be projected. If a holography pattern type is selected, a holography image 1833 having a pattern vary in accordance time may be projected.

In the following description, a detailed configuration of the present invention is explained with reference to the accompanying drawings.

First of all, the step S1710 of setting a holography type for a specific object or screen will be described in detail with reference to FIGS. 19 to 23.

Secondly, the step S1720 of giving a visual effect to a holography type set specific object or screen will be described in detail with reference to FIGS. 24 to 28.

Thirdly, the step S1730 of selecting a holography type set specific object or screen and the step S1740 of projecting a holography image in accordance with a set holography type will be described in detail with reference to FIGS. 29 to 34.

The step S1710 of setting a holography type for a specific object or screen is described in detail as follows.

As mentioned in the foregoing description, a holography type settable for a specific object or screen may be classified into a default type, a holography background type and a holography pattern type.

A method of setting a holography type is described with reference to FIG. 19 as follows.

FIG. 19 is a diagram for one example of setting a holography type for a specific object or screen according to one embodiment of the present invention.

FIG. 19A shows one example of setting a default type. In particular, it may be able to set whether a content related to a specific object or screen will be intactly projected as a holography image.

If a default type is not set (i.e., ‘OFF’ 1911], a content related to an activated specific object or screen is not projected as a holography image [1912].

If a default type is set (i.e., ‘ON’ 1913), a content related to an activated specific object or screen is projected as a holography image [1914].

Although FIG. 19A shows that a setting of a default type and a setting of activation or deactivation of a holography image itself are performed at the same time, the settings may be separated from each other.

In particular, the holography image projection is set but the default type may not be set.

FIG. 19B shows one example of setting a holography background type.

Referring to FIG. 19B, a user may be able to set holography backgrounds in various forms via a holography background type setting menu 1921. In doing so, a plurality of settable holography backgrounds may be provided as thumbnails to a user [1922].

FIG. 19C shows one example of setting a holography pattern type.

Referring to FIG. 19C, a user may be able to set various kinds of holography patterns via a holography pattern type setting menu 1930.

Representatively, by changing a distance difference between a holography output module and a holography image in accordance with time, it may be able to set a holography pattern 1931.

And, by changing a shape of a holography image projected by the holography module 156 in accordance with time, it may be able to set a holography pattern 1932.

Moreover, by changing both a distance difference between a holography output module and a holography image and a shape of a holography image projected by the holography module 156, it may be able to set a holography pattern 1934.

Besides, as mentioned in the foregoing description, it may be able to set a holography pattern by moving a projected holography image in right and left directions, rotating a projected holography image, or changing a color or size of a projected holography image in accordance with time.

Meanwhile, regarding a holography type, a holography type setting menu may be changed in accordance with a holography type supported by a terminal. This is explained with reference to FIG. 20 as follows.

FIG. 20 is a diagram for a detailed example of a holography type settable according to one embodiment of the present invention.

Referring to FIG. 20, in case that a terminal supports a holography image projecting function only, a holography type setting menu 2010 may be provided [FIG. 20A]. In particular, a default type may be set via the holography type setting menu 2010 only.

In case that a terminal supports a holography background image function, a holography type setting menu 2020 may be provided [FIG. 20B]. In particular, a user may be able to set a prescribed one of a plurality of holography backgrounds in the default type.

In case that a terminal supports a holography pattern function, it may be able to provide a holography type setting menu 2030 [FIG. 20C]. In particular, it may be able to set a holography image to be projected in accordance with one of a plurality of holography patterns in the default type.

In particular, a user may be able to set various holography types by selecting one of a default type 2041, a holography background type 2042 and a holography pattern type 2043.

A user may be able to set a specific target or screen, for which a set holography type will be applied, in detail. This is described with reference to FIG. 21 as follows.

FIG. 21 is a diagram for one example of setting a holography type for a specific object according to one embodiment of the present invention.

Referring to FIG. 22A, a user may activate a holography setting related menu 2210 via a specific menu.

Referring to FIG. 22B, it may be able to select a menu 2220 for adding an object for which a holography type will be set.

Referring to FIG. 22C, if the menu 2220 for adding an object for which a holography type will be set is activated, a plurality of objects, for which a holography type can be set, are displayed as a list 2230 by being sorted by category. In doing so, the user is able to select a widget category.

Referring to FIG. 22D, if the widget category is selected, the controller 180 may display a plurality of widgets saved in the terminal. The user may be then able to select a photo frame widget 2240 from a plurality of the displayed widgets.

Referring to FIG. 22E, if the photo frame widget 2240 is selected, a menu 2251 for selecting a holography type to set for the photo frame widget 2240 is activated. The user may be then able to select a holography background type 2252 from a default type, the holography background type 2252 and a holography pattern type.

Referring to FIG. 22F, if the holography background type 2252 is selected, holography backgrounds in various forms may be provided to the user. In particular, the user may be provided with holography background information as a list of holography background names [2261], holography background information as thumbnails [2262] or holography background information as thumbnails and preview [2263].

Referring to FIG. 22G, if the user selects a prescribed holography background, a menu 2271 for selecting a photo, which will be included in case of activating the photo frame widget 2240, is activated. In doing so, the user may be able to select at least one image which will be included in case of activating the photo frame widget 2240 [2272].

Referring to FIG. 22H, a visual effect, which will be explained later, is displayed on an image 2280 to which a holography type is applied.

Referring to FIG. 22I, if the holography type set image 2280 is selected by the user, a plurality of images, which will be included in case of activating the photo frame widget 2240, are projected as holography images 2291 and 2292 in accordance with predetermined time, respectively.

Meanwhile, the holography type may be set by a specific object or group unit using a phonebook.

FIG. 23 is a diagram for one example of setting a holography type by a specific target or group unit according to one embodiment of the present invention.

Referring to FIG. 23B, while a group menu 2321 is active, a user makes a search for a specific object or adds a specific group and may be then able to instantly set a holography type for the found or added specific object via a holography type setting menu 2322.

Therefore, the user may be able to conveniently set a holography type by a specific target or group unit.

Meanwhile, the step S1720 of giving a visual effect to a holography type set specific object or screen is described in detail with reference to FIGS. 24 to 28 as follows.

As mentioned in the foregoing description, the visual effect plays a role as an indicator in informing a user that the holography type is set for the corresponding target. This visual effect may be implemented using various effects including a pattern of surface texture, flickering, size variation, at least one shape-transformed or twisted portion and the like.

For clarity and convenience of the following description, assume that a holography type is set to a holography background type and that a set background is displayed as a shortcut or thumbnail. Besides, the visual effect is non-limited by the above-mentioned effects. And, the visual effect may be implemented using other effects in various ways.

Referring to FIG. 24A, since a holography background type of a rectangular shape is set in association with a camera application, a shortcut visual effect 2411 of a rectangular shape is displayed to indicate the holography background type setting. In particular, since the shortcut visual effect 2411 of the rectangular shape in prescribed size is displayed on a left top end portion of the album icon 2412, a user may be able to easily recognize that the holography background type of the rectangular shape is set for the album application.

Referring to FIG. 24B, an icon for a holography background type set application may be displayed in a manner of being substituted with a shortcut visual effect corresponding to the set holography background type.

In particular, assuming a case that a different holography background type is set for such an application as an album, a music, a game, a camera and the like, shortcut visual effects 2420 in accordance with the set holography backgrounds may be displayed, as shown in FIG. 24B, in a manner of being substituted for the original icons, respectively.

Therefore, a user may be able to conveniently identify a holography background type set application from other applications with ease.

Referring to FIG. 24C, an additional visual effect may be displayed in accordance with a kind of each of the set holography types.

For instance, a default type among a plurality of holography types may be further provided with a visual effect ‘D’, a holography background type among a plurality of holography types may be further provided with a visual effect ‘S’, and a holography pattern type among a plurality of holography types may be further provided with a visual effect ‘P’.
